MURRAY, F'ALPENA,MICHIGA Y To all whom my concern:

' ing- Cartridges; and we do' hereby solid body, whereby the same handled and alpplied to use.

Beit known that We, GEORGE WoLsEY and L oUIs FUssELcitizens of the United States, residing at Al ena, inthe county of Alpena and State of ichi an, have invented certain new and useful' mprovements in Blastdeclare thet following tov be a full, clear, and exact description of .the invention, such as will en- .able others skilled in the-art pertains to make and use the same. 1

ur invention relates toV new and useful improvements in explosives and more particularly to that class adapted to be used for blasting pur oses and our object is to providev means or forming the explosive into a may be readily A further o ]ect is to so treat forming the body, as to render the same of a v llow detonating quality and at the'same time maintain its `high explosive qualities and a v still further ob'ect is to provide a suitable detonator of a Y through the body',- whereby Mor similar light igh detonating' quality and place the same 1n an opemng. extending the detonator will be protected by the body.

Other objects and advantageswill be hereinafter referred to and more vparticularly pointed out in the claim,

In-the accompanying drawings which are made a part ofthis application, Figure l is a perspective lView of our im roved form of explosive ready to be applic to use. Fig. 2

Referring to the drawings in which simi-.-

form of fuse 6.

' In forming the v1body 2 of the explosive, .i

weemploylpicric acid, which is first melted.

and then poured into the casing 1, where the compound remains until it becomes cooled and hardened. p formed lengthwise of the body in any preferred manner, as by boring with a bit or auger, said o ening preferably extending the ful-l length of the body and adapted to 'receive the detonating substance 4, the body -when thus formed, while maintaining a high grade of explosive power, 'is of a low gra-de of detonatingpower, so that the explosive may be readily handled without exploding thesame. l ,l

In constructing means for explodingthe body, we provide a detonator of a high grade of detonating power and to this end we employ one part salt-peter, one part aqueous solution ammonia the strength of the ammoniabeing, about 10 per cent. and three parts picric acid, unmelted, the.v solid ingredients being finely pulverized and thoroughly commingled with `the liquid ingredients, after which the product so produced is entered into the opening 3, and said opening filled from end to end. AAfter this is accomplished, the usual form of cap 5 and fuse 6 are placed in coperation with the detonating substance, or, if preferred, any suitable-form of electrical appliance may be employed- Vfor exploding the detonator;

.The opening 3 is then a' very strong explosive and at the same time provided means for preventing the casual explosion of the compound, thereby rendere ing the same safe to handle without the danQ ger of a premature explosion and .1t w1ll further be seen that by placing the low grade of detonating material around the high grade 'of detonatin material, the same cannot, be readilyexp o ded, except by the use vof the usual form of cap and fuse', or similar exploding devices.
